GIRVAN STW Wastewater Treatment Plant, Girvan, Scotland

GIRVAN STW is a wastewater treatment plant located in Girvan, South Ayrshire, Scotland, serving a population of around 13,851. The facility is part of the United Kingdom's wastewater infrastructure, managed by Scottish Water, and plays a key role in protecting public health and the environment in this coastal region. As a plant serving a medium-sized agglomeration, GIRVAN STW is expected to meet the treatment standards set by the Urban Waste Water Treatment (Scotland) Regulations, which transpose the EU Urban Waste Water Treatment Directive. These regulations require secondary treatment for discharges to freshwater and estuaries, with more stringent tertiary treatment in sensitive areas. The plant's designed capacity is 1.00 (likely in megalitres per day or similar unit), indicating its scale. The treated effluent from GIRVAN STW is discharged into the local water environment, which ultimately drains to the Firth of Clyde and the Irish Sea. This coastal discharge requires careful management to protect marine ecosystems and comply with environmental quality standards. The plant contributes to the overall health of the River Girvan and the surrounding coastal waters, supporting biodiversity and recreational uses.

GIRVAN STW discharges into the River Girvan, which flows into the Firth of Clyde and then the Irish Sea. The Firth of Clyde is a complex estuarine environment supporting diverse marine life, including fish, shellfish, and seabirds. The area is ecologically sensitive due to its role as a nursery ground for commercially important fish species and as a habitat for migratory birds. Proper treatment of wastewater is essential to maintain water quality and protect these downstream ecosystems.
